Chris Trousdale is a former boy band member who was in Dream Street with Jesse McCartney, but now works at a sushi restaurant. He sings The Wanted's Glad You Came, and strays from The Voice norm by adding in some boy band-approved dance moves. Sadly, none of the coaches are impressed by his vocals.
GIF (n.). The Graphics Interchange Format, one of the most popular standardized formats for storing graphic data in binary computer files. The standard has been revised several times, and includes provisions for interlacing and animating images. Its disadvantage is that it can store only 256 colors. Compare JPEG.
Steve Wilhite created the Graphics Interchange Format, or GIF, while working for Compuserve in 1987. When he received a Webby Award in 2013 for it, and delivered his five-word acceptance speech (that's all the Webbys allow), he flashed a GIF on the big screens at the Cipriani Wall Street in New York.
